DEVICE FOR REMOVING S NOW FROM SIDEWALKS, 80c.

SPECIFICATION forming part of Letters Patent No. 275,684, dated April 10, 1883.

Application filed November 13, 1882.

is pushed forward, the ascent of the snow in the scoop being aided by endless chains to which paddles are pivoted, as fully described hereinafter.

In the accompanying drawings, Figure 1, Sheet 1, is a side view of the machine; Fig. 2, a vertical section; Fig.3,Sheet 2,a plan view;

and Fig. 4, a side view of the sweeping attachment.

The frame A of the machine is constructed to carry a box or reservoir, B, into the front end of which is fitted and secured the fixed rear portion, a, of the inclined scoop D, the front portion, a, of which is arranged to be in contact, or nearly so, with the sidewalk or other path to be cleared of snow, this front portion of the scoop being so connected to the fixed part of the same that it can be detached therefrom when necessary.

The machine is carried by front wheels, I), and rear wheels, 01, adapted to suitable axles, and through posts eof the frame, and through the fixed portion of the scoop passes a shaft, f, to which are secured the two chain-wheels G, two endless chains, H, passing round the wheels and round similar wheels, J, on a shaft, h, which has its bear-in gs in brackets i, secured to the posts 7c of the frame. The shaft f is driven from the wheels at in the present instance by the connecting-rods j-one on each side of the machine-one end of each rod fitting on a pin attached to the wheel or on the pin of a crank on the axle, and the other end embracing the pin of a crank on the shaft f. The shaft f may, however, be driven from the wheels or axles by bands or suitable gearing.

Paddles Ktwoin the present instance-ex- (No model.)

tend across the two chains to which the hubs of the said paddles are pivoted.

As the machine is wheeled forward from the rear over the path, the snow will ascend the scoop, but in the absence ofthe chains and paddles would present such resistance to the ef' forts to push the machine forward as to render this operation difficult. The paddles,however, as they are carried round with the chains, afford the desired relief, for as each paddle traverses in the direction of the arrow,with its outer edge nearly in contact with the bottom of the scoop, it pushes the snow before it into the reservoir, the projecting portions m of the paddle bearing against the chains, so that it cannot turn on its pivot until it passes round the pulleys G with the chains, leaving behind it in the box the snow, the ascent of which in the inclined scoop it has promoted. The box B is not secured to the frame A, but simply rests thereon, so that it may be drawn rearwardly from said frame when necessary, and emptied of its contents by being overturned.

When the machine has to be converted into a sweeper to clear away such of the snow v the rods j in such case being detached from the operating-crank and supported by books or pins on the frame, as shown by dotted lines in Fig. 1. A frame, N, which is pivoted at p to the two posts 6 of the frame A, and which has hitherto been confined by hooks to posts to in the position shown in Fig. 1, is now turned over in the direction of the arrow toward the front end of the machine, where it becomes a medium by which the machine can be pushed 9 P, which is hinged aty to the main frame, the hinged frame being provided with segmental IOO plates R, secured to the posts 10 by set-screws e, which pass through segmental slots in the plates, and thus permit the hinged frame, and with it the brush,t0 be raised or lowered at pleasure and secured after adjustment.

I claim as my invention 1. Thecombination of the wheeled frame and the box with a scoop made in two partsone fixed, the other detachablesubstantially as specified.

2. The combination of the scoop, chainwheels, and chains, with paddles K, pivoted to the said chains, and having projections m, for bearing against the same.

3. The combination of the wheeled frame with the pivoted frame 1, carrying bearings for the journals of a rotary'sweeper, and with devices by which the said pivoted frame can be In testimony whereof I have signed my name 0 to this specification in the presence of two subscribing witnesses.
